Dr. Jeremy Stewart

Lab director


Dr. Jeremy Stewart has devoted his career to understanding the development and progression of mental health disorders in adolescents and young adults. Using a multi-modal approach grounded in clinical psychological science and neuroscience methods, he aims to uncover new insights regarding the cognitive, emotional, and behavioural processes that contribute to psychopathology in youth. Jeremy strives to translate his findings to enhance assessment and interventions for young people coping with mental illness, and ultimately, to improve well-being.

Jeremy’s most recent work is geared to understanding the onset and worsening of suicidal thoughts and behaviours, particularly. Suicide science faces many challenges. Among them is the fact that most people who think seriously about suicide will not make attempts, and most strong predictors of suicidal thoughts (e.g., depression) tell us little about who is most likely to act on these thoughts. Consequently, guided by a developmental psychopathology framework, Jeremy’s research aims to identify risk factors that cut across diagnostic boundaries that may contribute to the escalation from suicidal thoughts to actions. As this transition is a pivotal target for suicide prevention, Jeremy hopes that his findings will contribute to curbing unnecessary and preventable loss of life.

Presently, Jeremy is appointed as an Assistant Professor in the Department of Psychology at Queen’s University in Kingston, Ontario. His research team—the Queen’s Emotions and Risky Behaviours in Youth (QuERBY) Laboratory—is a dynamic group of junior scientists committed to improving the safety and well-being of Canadian youth through leading-edge research; local (e.g., campus), provincial, and national knowledge translation; and advocacy. Overall, Jeremy is privileged to have such an inclusive, professional, and hard-working lab who share his enthusiasm for psychological science!

Natasha Drobotenko [cv]

Natasha is a first-year MSc student in the Clinical Psychology program. For her master’s thesis, she is investigating suicide risk among people with diverse gender identities and expressions. Her research interests include assessing risk factors for suicidal behaviour and non-suicidal self-injury in adolescents and young adults, with a focus on cognitive processes, negative urgency, and adverse childhood events.

Emilia Sherifi

Emilia is a first year Clinical Psychology MSc student. Her master’s thesis will aim to assess risk factors for suicidal behaviour, and will likely involve Ecological Momentary Assessment. She is particularly interested in the role of impulsivity, emotion regulation and stressful life events in suicide within youth.
